Sometimes, when create ticket from email, the ticket fall in dead cycle, which cause the Spiceworks service shutdown, and the size of related data/uploads/ticket/ticket# folder increased to several M bytes. And after started the service, tried to delete the ticket via Settings->Help Desk, the system service shutdown again.

What is the reason? Is there any solution to solve the issues like this forever. This increase a lot of IT labor cost to maintain the system?
